Things can go wrong, but usually there is an error message, or an ever-spinning circle, not just a black screen.
The first question is what is your setup?
Who is your ISP, what device are you running the Now app on, and what make and model of TV is in use here?
The second question is what steps are you taking, in what order, that give rise to this issue? What programme(s) from what membership(s) are you trying, and do you have Boost?
Then we can try, as best we can, to reproduce the problem, or to figure out what might help you correct or avoid it.
Set a Payment PIN on your account so that no-one but you can buy memberships on it.
Check your bank accounts monthly for any other unexpected payments to Now.
That way you can at least nip them in the bud, while you and Now figure out whose fault they are.
